WHY PLOTER SHOWS 2 CHANNEL DATA

[aqildad-create]

below is code were i am convert i2s to single channel data then why is plotter showing 2 channel data ?I didn't fill both channel . I was just testing the code and functionality

IN MY CASE It should be single channel data while the second channel should empty .

#include "AudioTools.h"
#include "AudioLibs/AudioA2DP.h"
CsvOutput<int16_t> out(Serial, 2); // ASCII stream as csv

I2SStream i2sStream; // Access I2S as stream

FormatConverterStream conv(out);

StreamCopy copierr(conv, i2sStream);

void setup(void) {
Serial.begin(115200);

auto config_in = i2sStream.defaultConfig(RX_MODE);
config_in.i2s_format = I2S_STD_FORMAT; // or try with I2S_LSB_FORMAT | I2S_STD_FORMAT
config_in.is_master = true;
config_in.use_apll = false; // try with yes
config_in.pin_mck = 3;
config_in.bits_per_sample = 32;
config_in.channels = 2;
config_in.sample_rate = 44100;
i2sStream.begin(config_in);
AudioInfo from(44100, 2, 32);
AudioInfo to (44100, 1, 16);

conv.begin(from, to);

}
void loop() {

copierr.copy( );

}

Because you defined it to be 2 channels in the constructor
